This patch fixes the following inconsistencies in bond_release_all:
- IFF_BONDING flag is not stripped from slaves
- MTU is not restored
- no netdev notifiers are sent
Instead of trying to keep bond_release and bond_release_all in sync
I think we can re-use bond_release as the environment for calling it
is correct (RTNL is held). I have been running tests for the past
week and they came out successful. The only way for bond_release to fail
is for the slave to be attached in a different bond or to not be a slave
but that cannot happen as RTNL is held and no slave manipulations can be
achieved.
V2: As suggested bond_release is renamed to __bond_release_one with a
new parameter "all" introduced so to avoid calling unnecessary code while
destroying a bond, and a wrapper for it called bond_release is created
because of ndo_del_link. bond_release_all() is removed.

netbk_fatal_tx_err() calls xenvif_carrier_off(), which does
a xenvif_put(). As callers of netbk_fatal_tx_err should only
have one reference to the vif at this time, then the xenvif_put
in netbk_fatal_tx_err is one too many.

Check whether the phy-reset GPIO is valid, prior to requesting it.
In the case a board does not provide a phy-reset GPIO, just returns immediately.
With such gpio validation in place, it is also safe to change from pr_debug to
dev_err in the case the gpio request fails.

The 3ad machine state spinlock can be used before it is inititialized
while doing bond_enslave() (and the port is being initialized) since
port->slave is set before the lock is prepared, thus causing soft
lock-ups and a multitude of other nasty bugs.

port->slave can be NULL since it's being initialized in bond_enslave
thus dereferencing a NULL pointer in bond_3ad_update_lacp_rate()
Also fix a minor bug, which could cause a port not to have
AD_STATE_LACP_TIMEOUT since there's no sync between
bond_3ad_update_lacp_rate() and bond_3ad_bind_slave(), by changing
the read_lock to a write_lock_bh in bond_3ad_update_lacp_rate().

Bastian Bittorf reported that some of the silent freezes on a Linksys WRT54G
were due to overflow of the RX DMA ring buffer, which was created with 64
slots. That finding reminded me that I was seeing similar crashed on a netbook,
which also has a relatively slow processor. After increasing the number of
slots to 128, runs on the netbook that previously failed now worked; however,
I found that 109 slots had been used in one test. For that reason, the number
of slots is being increased to 256.

====================
The following patchset contain updates for your net-next tree, they are:
* Fix (for just added) connlabel dependencies, from Florian Westphal.
* Add aliasing support for conntrack, thus users can either use -m state
or -m conntrack from iptables while using the same kernel module, from
Jozsef Kadlecsik.
* Some code refactoring for the CT target to merge common code in
revision 0 and 1, from myself.
* Add aliasing support for CT, based on patch from Jozsef Kadlecsik.
* Add one mutex per nfnetlink subsystem, from myself.
* Improved logging for packets that are dropped by helpers, from myself.

Pull in 'net' to take in the bug fixes that didn't make it into
3.8-final.
Also, deal with the semantic conflict of the change made to
net/ipv6/xfrm6_policy.c A missing rt6->n neighbour release
was added to 'net', but in 'net-next' we no longer cache the
neighbour entries in the ipv6 routes so that change is not
appropriate there.

Connection tracking helpers have to drop packets under exceptional
situations. Currently, the user gets the following logging message
in case that happens:
nf_ct_%s: dropping packet ...
However, depending on the helper, there are different reasons why a
packet can be dropped.
This patch modifies the existing code to provide more specific
error message in the scope of each helper to help users to debug
the reason why the packet has been dropped, ie:
nf_ct_%s: dropping packet: reason ...
Thanks to Joe Perches for many formatting suggestions.

After discussion on the linux-sh mailing list and reference to the
hardware documentation it appears that 'TMU00', 'TMU01' and 'TMU02'
use a common clock.
The sh_tmu.1 portion of this change resolves a regression introduced in
58079fa7d5 (ARM: shmobile: r8a7779: Correct
TMU clock support) and fixes a regression introduced by that patch. That
patch is queued up for v3.9.
